Bull trout (Salvelinus confluentus) population structure and extent of hybridization with brook trout (S. fontinalis) across Alberta's Eastern Slopes
… fundamental in advancing our understanding of species conservation. Bull trout (Salvelinus confluentus), a charr native to northwestern North America, face population declines and require protection to ensure their persistence and survival. In my thesis, I used genetic loci known as Single …

The relationship between two species of fur seals Arctocephalus Tropicalis (Gray) and A. Gazella (Peters) on Marion Island
… lands, and appear to be hybridizing. Adult males of both species and the interspecific hybrids can be distinguished using univariate and multivariate analyses of cranial measurements. The two species differed in the electrophoretic mobility of the serum protein, transferrin. The extent of …

Genetic diversity and hybridisation estimates of Arctocephalus tropicalis and A. gazella from Marion Island
In this study, hypervariable region I (HVRI) of the mitochondrial DNA (mtDNA) control region, and five microsatellite loci were used to assess genetic variability and the extent of hybridization between the two fur seals (Arctocephalus tropicalis and A. gazella), that occur on Sub-Antarctic Marion …

Incorporation of Physico-Chemical Parameters Into Design of Microarray Experiments
… provide sensitive and specific detection of gene expression and are becoming a popular experimental platform. In the process of designing an oligonucleotide microarray for Brucella, we optimized the overall design of the array and created probes to distinguish among the known Brucella …

Population genetics of Michaux's sumac, smooth sumac, and their hybrids
… to the southeastern United States, with two of the largest populations located at Maneuver Training Center--Fort Pickett, VA (Fort Pickett), and a nearby property, Deepwater. Michaux's sumac requires soil disturbance and fire to maintain healthy populations. Before being added to the …

Bighead and silver carp hybridization in the Mississippi River Basin: prevalence, distribution, and post-zygotic selection
Hybridization is a pervasive evolutionary phenomenon in plant and animal taxa. Understanding the evolutionary consequences of hybridization is dependent upon the ability to adequately detect genetically admixed individuals, characterize the maternal contribution and structure of hybrid zones, and …

Assessment of Walleye, Sauger, and Black Bass Populations in Lewis and Clark Lake, South Dakota
The relationships between year-class strength of walleye Stizostedion vitreum and sauger s. canadense, as indexed by age-0 seine catch per unit effort (CPUE) , and environmental variables were assessed in Lewis and Clark Lake, South Dakota, from 1985 through 1994. Significant (P≤0. 10) correlations …
